Mobile Water Park

I would like to start a small business for mobile water parks and I am looking for experts in managing water that will be used in the park. I will be working in places where water is quite expensive in both sourcing it and recycling.  It is very important to handle the hygene, safety, and health issues. What technologies would you recommend? What sources of information is there? Can you recommend a consultant to work with me? Looking forward to experts as well as service providers. Thanks and regards,
